I live on a small new build estate, there are loads of children running around screaming and generally being kids which is fine. Except I just came home and found a few of them throwing stones at a cat that was hiding under a caravan. This makes my blood boil, animal cruelty is not on in any shape or form. So I walked up and calmly stated 'don't throw stones at the cat, ive just seen you do it and it isn't nice'. They looked at me sheepishly and I walked away and left it at that.
I don't know the children in question so was IBU to say something?
